Katsky Korins Listed by meow Ransomware Group

If you are a customer of Katsky Korins, here’s what is being claimed, and what it would mean for you.

Katsky Korins was listed on Meow's leak site. Meow claims to have stolen internal data. This is the group's claim, not a confirmed finding.

Katsky Korins Listed by meow Ransomware Group

On November 26, 2023, New York law firm Katsky Korins appeared on the leak site operated by the meow ransomware group. The listing states that internal files were exfiltrated during a ransomware attack and threatens to publish them unless the firm meets the attackers’ demands. The disclosure does not specify how many individuals or records are affected, nor does it list exact data types beyond “internal files.”

You can’t unleak data. You can take away what it’s worth.
A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 582 companies.

Details from the Leak-Site Listing

The meow leak site entry for Katsky Korins states the firm was hit by a ransomware deployment and that attackers successfully removed data before encryption. No victim count or detailed inventory of stolen material is provided. The posting includes a deadline for payment, after which the group says it will begin releasing the exfiltrated files. As with most ransomware leak sites, the exact volume and sensitivity of the material remain undisclosed in the public listing.

Internal files exfiltrated is the only description given. This phrasing typically covers documents, spreadsheets, emails, contracts, and client-related records that law firms routinely store on their networks.

Why This Matters for You and Your Family

When a law firm’s internal files are stolen, the exposure often reaches beyond the business. Clients, employees, vendors, and their families can have personal information entangled in those records. If your name, address, Social Security number, financial details, or family information appears in correspondence, billing records, or case files held by Katsky Korins, that data may now sit on a ransomware operator’s server. Even if you never directly hired the firm, shared information through a partner, employer, or joint legal matter could place you in the exposed dataset.

The uncertainty itself creates risk. Without a published record count or data inventory, anyone connected to the firm must assume their information could be included until proven otherwise.

Doxxing and Identity-Chain Implications

Stolen internal files frequently contain more than isolated records. They can link email addresses, phone numbers, home addresses, dates of birth, and client notes that map one identity to another. Attackers and data brokers routinely combine these fragments into full identity chains. A single leaked email can surface linked gaming accounts, social-media handles, and family-member details. Once assembled, this chain fuels doxxing, targeted phishing, account takeovers, and identity theft that can affect every member of a household.

Credential leaks like this one cascade into account takeovers and doxxing chains, especially when gaming accounts belonging to children reuse passwords or security questions drawn from family legal or financial documents.

Meow Ransomware Group’s Known Track Record

Public reporting attributes the meow ransomware group with emerging in late 2022. The group is known for relatively quick attacks focused on small-to-medium businesses, including professional-services firms. Their typical playbook involves initial access through compromised credentials or unpatched remote desktop services, followed by exfiltration of sensitive files before deploying ransomware. Meow then uses dual-extortion tactics: demanding payment to prevent file publication and, in some cases, threatening to notify the victim’s clients directly. Prior victims have included healthcare providers, manufacturers, and other law firms, though exact success rates and total ransom amounts remain opaque because many incidents go unreported.

What to do

  • Run a DoxxScan to map every link between your emails, phone numbers, handles, and real-world identity, then use the cleanup of Warden to remove what you can.
  • Rotate any password you ever used at Katsky Korins or related services and enable 2FA through an authenticator app instead of text messages.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure surfaces in hours rather than months.
  • Cover the household with DoxxScan family protection that extends to dependents and children’s gaming accounts often chained to the same leaked address or parent credentials.
  • Let remediation specialists handle ongoing takedown requests for any personal records that surface on data-broker or extortion sites.

The Katsky Korins incident shows how quickly a single professional-services breach can ripple into long-term personal exposure for clients and their families. Staying ahead requires more than reactive checks; it demands continuous visibility and expert help when new leaks appear. DoxxScan by GalaxyWarden delivers that combination through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts. Start your DoxxScan trial today and treat this claimed breach as the last time your family’s information stays unprotected.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
